Maybe I misunderstand what is supposed to happen, but I believe that
if the function is marked VARIADIC then the second case would in fact
be rejected: the signature of the function for parameter-matching
purposes is text followed by one or more ints, never text and int[].

I think a is just text[], full stop.  Only the last parameter is
interpreted differently for variadic.

Your point about the syntax is good though.  It would be better if
the syntax were like

        create function foo (a text, variadic b int[])

or maybe even better

        create function foo (a text, variadic b int)

since (a) this makes it much more obvious to the reader what the
function might match, and (b) it leaves the door open for marking
multiple parameters as variadic, if we can figure out what that means.
